'IMPROVEMENT IN BURRINGFMACHINES.

Specification forming part of Letters Patent No. 210,565, dated December3, 1878;` application filed Julie 13, 1878.

To all whom it may concern:

Be it known that I, FREDERICK G. SAR- GENT, of Graniteville,.in thecounty of Middlesex and State. of Massachusetts, have invented certainImprovements in Machines for Burring Wool, 85o., of which the followingis a specification My invention relates to wool-burrin g machines 5 andthe improvements consist in means for conducting the buffs and woolwhich are thrown from the upper burring-cylinder by its guard out fromabove the gift through passages formed in the sides of themachine, andback into the machine below the gift; iu the employment, in combinationwith the side passages, of a tube or pipe passing from the case, inwhich ismounted one ofthe brushes, into the top of the machine above thegift, whereby the blast of said brush is caused to assist in forcing thebuffs and wool through the side passages, as mentioned; and in the useof a swinging or adjustable gate below the lower guard or knocker, toregulate the draft of the fan, all as hereinafter explained.

In the accompanying drawings, Figure l represents a longitudinalvertical section of my improved machine, and Fig. 2 a horizontal sectionof the same on the line w a: of Fig. 1.

In its general construction and mode of operation the machine is similarto those in common use, as will be seen by reference to the accompanyingdfawin g, in which- A represents the frame of the machine, and B the'beater or picker cylinder, which takes the wool from the feed-rolls aand delivers it to the burring-cylinder C, from which it is swept bythebrush D and deliveredto the burring-cylindef E. From the cylinder E thewool is swept by the brush F and delivered from the machine in the usualmanner, guardcylinders b and c being employed to knock the buffs fromthe wool on the cylinders C and E, as usual. The bui-rs and bits of woolwhich are thrown from the cylinder E by the guard or knockef c fall uponthe transverse gift or partition I, which is clos'ed or made solidacross its entire face. From the upper side of the gift or partition Ithe burrs are conducted out through the side or sides of the machine,and carried through pipes or passages Il back into the machine below thegift, as represented in Figs. 1 and 2.

In order to force the buffs and bits of wool 'through the passages d, Iemploy, in addition to the usual suction-fan G, mounted on the a spoutor pipe, H, extending from the case in which the fan is mounted downthrough the top of the machine, its mouth opening directly over the giftI, as shown in Fig. 1. l The blast ,from the brush F greatly assists thefan G in `forcin g the bufrs from the gift 'or partition I, and throughthe passages d, while by thus carrying the buffs around instead ofthrough the gift, they are caused to interfere less with thepicker-cylinder, and the action of themachinc is otherwise improved.

In some cases I find it desirable to form small openings g in the sidepassages, d, for the admission of air from the outside of the machine,but these may be omitted, if desired, or they may be furnished withcovers, by which they may be opened or closed at pleasure.

In practice I prefer to form the side passages, d, by means of a hood ofcap extending over and joining one or more openings in the side of themachine, both above'aud below the gift, though' any other constructionmay be employed, if desired. f

In order that the draft of the fan G may be regulated for operating uponlight or heavy Wool, and also for the purpose of more perfectlyseparating the buffs and bits of wool which are thrown from theburring-cylindef C, a swinging or adjustable gate, J, is mountedtransversely in the frame of the machine, below the lowerguard-cylinder, b. By changing the inclination ot' this gate J, the sizeof the opening in the end of the machine is regulated and the draft ofthe fan G controlled. The buffs which are thrown oi by the guardcylinderb, or a portion of them, fall upon the inclined gate J, which, whenplaced at a proper inclination, causes them to roll down and falloutside of the machine, their weight overcoming the draft of the fan G,while' the bits of wool, being lighter, are drawn into the machinethefeby. 4

A slotted plate or slide, c, clamped to the frame of the machine by ascrew, f, is arranged to support the free edge ot the gate J and sustainit at the desired inclination 5 but it is apparent that this, togetherwith other details, may be modified, the essential features being thecarrying of the burrs, Src., around instead of through the girt, and theregulation of the draft.

Having thus described my invention, what I claim is l. Inaburring-machine, the combination of a girt or partition located betweenthe picking and burring cylinders, a passage, d, at one or both ends ofthe girt, and a fan arranged to produce a current of air through saidpassage or passages, substantially as shown, whereby the burrs andparticles ot fiber are carried outward at the ends of the girt andreturned into the machine on the opposite side of the girt.

2. In a burring-machine, the combination of the side passage orpassages, d, located substantially as shown and described, a passage, H,and brush F, said passage H extending from the brush into the machine,for the purpose of conducting the blast from said brush inward, toassist in delivering the burrs through the side openings.

3. In a barring-machine, the combination of the cylinders E c, brush F,girt I, side passage or passages, d, and exhaust-fan G, substantially asshown and described.

4. The combination, in a barring-machine, of a transverse girt orpartition, located in front of a burring or guard cylinder, with sidepassage or passages, d, to return the burrs from said cylinder into themachine in advance ofthe girt.

5. The combination, in a burring-machine, of a suction-fan, Gr, a girt,I, arranged substantially as shown and described, and a passage, d,around the end of the girt, and provided with an air-inlet, g,substantially as set forth.

6. The combination, in a burring-machine, of a suction-tan, appliedsubstantially as shown and set fort-h, with the adjustable board or gateJ, located as shown and described, to control the admission of air.

7. The combination, in a burring-inachine, of an inclined board, J,adjustable as to its degree of inclination, with the guardcylindcr andfan, all operating` to assist in e'ecting a separation of the burrs fromthe ber, as set forth.
